A bedside clinical tool using creatinine kinetics to predict worsening renal injury and early recovery.

Background: Changing creatinine concentrations during acute renal failure are often confusing to clinicians to interpret and can cloud the patient's true current state of renal injury. By modifying the formula for kinetic estimate of glomerular filtration rate (KeGFR), a simple bedside clinical tool can be used to identify subtle changes in renal function.

Methods: The KeGFR was rewritten to instead calculate a predicted peak creatinine after renal injury.
